Norton 66252843614 Type 27 Grinding Wheel 5x0.25x0.875 in

Product Description

The NORTON 66252843614 is a Type 27 depressed center grinding wheel designed for metal grinding and material removal applications. Built with an aluminum oxide abrasive grain, this wheel delivers consistent cutting action on ferrous metals and mild steel. The 5-inch diameter, 0.25-inch thickness, and 0.875-inch arbor bore make it a standard fit for 5-inch angle grinders used by fabricators, welders, ironworkers, and general metalworkers. The depressed center profile keeps the grinding face angled for aggressive stock removal while maintaining clearance between the tool body and the workpiece surface.

This wheel is suited for weld blending, surface grinding, and deburring on structural steel, pipe, plate, and sheet metal in fabrication shops, construction sites, and maintenance facilities. It is sold in bulk case quantities and is appropriate for both production grinding environments and job-site use where consistent wheel performance across multiple passes is required. Licensed tradespeople and experienced metalworkers are the primary installers and end users of this product.

Installation Notes

Mounting of abrasive grinding wheels must be performed by qualified personnel following ANSI B7.1 safety standards and the grinder manufacturer guidelines. Before installing, inspect the wheel for cracks or chips and perform a ring test. Ensure the grinder is unplugged or locked out before changing wheels, and verify that the grinder spindle speed rating meets or exceeds the wheel maximum RPM.
